Possible Causes

Obstructed chimney or vent pipe, Blocked intake on direct vent models, Tripped blocked vent switch, Failed vent pressure switch

How to Fix / Troubleshooting

Safety: A blocked vent can cause carbon monoxide buildup. If you suspect flue gases in the living space, evacuate and call emergency services. Do not operate the boiler until the vent is verified clear.

  • 1. Visual inspection: From a safe location, inspect the vent termination and intake (if applicable) for snow, leaves, nests, or debris. Clear any obvious obstructions.
  • 2. Check blocked vent switch: Some Energy Kinetics boilers have a manual reset blocked vent switch on the flue. After clearing the vent and allowing the boiler to cool, press the reset button once.
  • 3. Do not bypass safeties: Never jumper or bypass a vent safety switch to keep the boiler running.

If the VENT BLOCK error returns, a professional must inspect the chimney, venting system, and draft.
